apple and mice don't get along?

problem is indeed with bluetooth mouse (in my case). I tried a bluetooth mighty mouse earlier, and I felt the same jerkiness / too high acceleration leading to overshoot your expectable pointer position (but maybe a little bit less than with my MS BT 5000 mouse)

@ hydrocianic: may you please tell me if I have to logout (from my session) after entering the string in the terminal? I felt that it did not apply after closing the terminal only....

Thanks

 

open terminal, type in the quoted line, press enter, reboot computer

for mine, after doing that a standard mouse become incapable of moving anywhere further than 300pixels on a standard mousepad area... but acceleration is eliminated.

 

Many thanks for your patience...


I have another question for all of you please: did anybody try the steermouse 3.9 program, downloadable from apple site? Does it help with respect to the acceleration issue? This behaviour is just a little bit p....me off as it is not recurrent but it happens only sometimes (pending how fast, maybe, i move the mouse) and it seems to be a little bit emphasized when a new window is opened or some graphics are being managed by OSX too: did you notice this too?

Cheers

 

since steermouse don't support my lachesis, i didn't pay too much attention to it; but from memory, steermouse is somewhat similar but i still find -1acceleration to be superior in precision w/ 4000dpi.

 

What happens after setting the acceleration at -1 is that the slider (on the OSX mouse preference pane) is set completely to the left, what should explain the fact that the pointer gets very slow, as you have already pointed out. In this configuration the mouse is almost unusable for me, that is the reason why I have decided to go for steermouse.

I have installed steermouse ans it seems to calm down the acceleration but, after a first feeling, with a small loss of precision. I will let you know after some more experience gathering.

Cheers

 

I have another question gents, please: it seems that my pointer tends to jerk a little bit (indeed gently overshooting for example the left upper buttons of a pane) when I have opened a new window or, as soon as I am moving it over animated features, it tends to overshoot a little bit. It is difficult to explain this behaviour, but did yo remark something similar?
Is it always due to the OSX acceleration features, or may it be due to the resolution of my mouse which should be a 1000dpi one? (it is a bluetooth microsoft 5000).

Thanks

 

Most likely caused by the latency of the bluetooth signal. Don't know of a way to fix that, although a wired mouse of a standard wireless mouse with a receiver would not experience this problem.

 

most of BT's complains are largely because there is a wake/sleep timer that conserves battery. the pointer will jerk a little from stationary to movement.

either that, or check the CPU usage on the programs you have

 

So does this mean that you have already heard something similar to my remark? What is strange is that this does not occur always and, after setting steermouse at certain values of sensitivity / speed, itthis behaviour is always there but very much less recurrent...it is a jerk of acceleration traducing into a kind of overshoot or of additional and undesired motion of the pointer sometimes......

it does not happen always and it is not indeed as soon as moving the mouse after a pause (I have also noted what you said) but it happens for instance after opening a window when I simultaneously move the pointer to some area of the newly opened window...it is not always. With respect to the CPU usage, this happens when there is nothing but Safari and airport opened.
I have also tried to remove the bluetooth.plist file and I will see what happens.

I believe anyway that it may exactly be the problem already remarked by other people about the not very familiar acceleration curve of OSX.

Last question: might this behaviour be a snagging signal of something randomly wrong in my apple bluetooth h/w? If it were the case, might it ever manifest under this behaviour of the pointer? The fact is that the jerk is so random and not very recurrent that it would be very difficult to show to an apple technician.

Last point: it might also be a problem of this microsoft mouse interfacing with OSX: I really wonder if it might be opportune to buy a mighty mouse for trial: what would you advise? (a lots of people say that MM is junk!!)
thank you for your help

 

it is not microsoft's issue for sure, BT's protocol should be standard.

there is no acceleration curve as far as i feel w/ 4mice i tried, but the acceleration is either "here" or "not".

safari was constantly hogging my CPU at 70% alone so make sure w/ the system monitor app under utilities. i am using firefox full time now, the first time after running a mac in my home and had safari deleted.

i would just go to buy a sidewinder G8 or mamba, or if you want driver support, get a deathadder and have all your settings customized. sidewinder has 5000(?)dpi so it will be more than enough even w/ -1a, so is mamba(5400dpi).

 

there should be anyway something 'wrong' or particular with bluetooth (either on mac or on microsoft mouse side) as the mouse behaviour is perfect after connecting a normal wired mouse...boh?

May the reset of PRAM + NVRAM be helpful or it is not even worth giving it a try in the light of all the complaints (about jumpiness of the pointer) done more or less by all other forumers in this thread?
Thanks for your advise
